Unfortunately, on Friday night we had to cut Douglas Kennedy's story about a U.S. soldier who mysteriously died in Afghanistan short. News on Olympic medalist Marion Jones' use of steroids broke just as Douglas's story was airing and we needed to break away to cover it. We are posting the entire story here:

• Video: Watch Douglas Kennedy's report

Army Spc. Ciara Durkin was found dead last Friday at Bagram Air Base, where she had been stationed in Afghanistan. She had been "in country" since February 2007 working in the finance unit of the Massachusetts National Guard.

The circumstances of her death are chilling: The single woman was found with a single bullet wound to the head. Weeks ago while home visiting her family she allegedly told them that if anything happened to her they should make sure it was investigated.

The Army has said that they are investigating Durkin's death as a homicide, though suicide has not been ruled out.

We sincerely hope that Spc. Ciara Durkin's family will soon learn what led to the death of the 30-year-old woman, daughter and sister who had eight siblings. Spc. Durkin and the many other brave men and women give up a great deal to serve our country in remote and often dangerous places. Her family deserves answers soon.
